Pre-Procedure

Before the colonoscopy test is done:

The bowel has to be as clear as possible so that the doctors can get a good view of the inside.

The patient has to avoid certain foods and medicines and the doctor might put him/her on a clear liquid diet (which includes green tea, juices, water, and clear broths) for one day or more.

Strong laxative tablets or solutions (such as Golytely or Nulytely) are also given to clean out the colon, and sometimes enema is also given. The laxatives start working very quickly and after taking them the patient might need to go to the bathroom frequently, so it is recommended that the patient stay at home before the day of the test.

The doctor will give you instructions prior to the colonoscopy test but if you have some concerns, you should talk to the doctor about it without any hesitation.

The patient should drink plenty of water, so that they do not get dehydrated.

The patient is not allowed to drive for 24 hours after the test, so he/she should arrange for a mode of transport beforehand.

During-Procedure

A gastroenterologist usually performs the colonoscopy procedure, with the help of an assistant.

It is either done in daycare procedure room or in the hospitalized patients (in ICU or ward setting too).

Medicines are given to the patient before the procedure commences. It helps the patient to relax and sleep during the test. The patient has to wear a gown and lie on their left side with their knees pulled up near the belly.

A colonoscope is inserted into the rectum of the patient. Air is pushed to inflate the colon, so that the camera can be inserted easily and the doctor can look at the lining of the colon clearly. The patient may feel abdominal spasms due to the inflation.

The camera in the colonoscope sends pictures to an external monitor.

The doctor examines the whole length of the colon and removes polyps (if any) and takes tissue samples for testing.

After the examination is over, the colonoscope is taken out of the colon.
